The earthquake was associated with the Bingai Fault System of the Southeast China Coast seismic zone. The Binhai Fault System, also known as the Littoral Fault System runs offshore in a north-northeast orientation for a total length of 500 km. Movement along the fault occurs in a right-lateral

. By modeling the earthquake and comparing the simulated seismic intensities against historical descriptions of the event, the

of the quake is estimated at 8.1 . The model estimates a maximum coseismic slip of 16–20 meters along with the Bingai Fault System. The rupture zone along the fault is estimated to be 250 km by 20 km.
